IMPROVEMENT IN IRON CURBS FOR STREETSl Specification forming part of Letters Patent No. 164,168, dated June 8, 1875; application iiled 'l December 3, 1 874.

To all whom it may concern:

Be it known that I, RICHARD EARRING-J TON, of Shenandoah, Schuylkill county, Pennsylvania, have invented certain new and useful Improvements in Curb for Streets, of which the following is a specification:

This invention relates to that class of curbing which is constructed in sections of cast metal 5 and my invention consists in making the sections of cast metal flat or with parallel sides in a single piece, with laterally-projecting perforated lugs at the ends, through which is passed a bolt for securing the parts together, a series of stays or laterally-projecting perforated flanges at the base or lower edge of the sections, which are designed to be placed upon a suitable foundation or support and to be secured thereto by means of spikes or keys driven through the openings or perforations in said stays or flanges, and a lateral horizontal ange extending the entire length, or nearly so, of each section for supporting the flagging or bricks,- all of which will be fully hereinafter described, the object being to secure a curbing of cast metal, each section embodying the above instrumentalities, whereby great strength is obtained, while the curbing is much lighter than any heretofore con structed.

In the accompanying drawings, Figure 1` represents a top or plan view of my invention; Fig. 2, a front elevation of the same; Fig. 3, a back elevation, and Fig. 4 a section, of the corner-piece employed in connection with my invention.

The letter A represents the straight fiat section of thejcurb, cast of a single piece, with a strengthening fiange, a, at its upper edge, laterally-projecting lugs B at each end, having a perforation, through which is passed a bolt, D, for the purpose of connecting the sections together. The base or lower edge of the flat sections are also cast with a series of stays or laterally-projecting iianges, E, each having a perforation, e, said flanges being designed to rest upon a suitable foundation, preferably of wood timbers, and to have spikes or pegs driven through the said perforations, in order to secure the curbing firmly and securely in place, and to prevent any liability of its being dislodged or moved from its posi at the end of each section, thereby providing a more secure, reliable, and substantial connection of the parts; but this feature is not absolutely essential, inasmuch as it may be dispensed with.

In connection with the cast-iron curbing, constructed as above described, I also propose to employ at the corners of the street a trap` front, G, which is cast somewhat wider than the curb-sections, so as to set down upon the top of the trap, and is provided with a lateral flange at its base or lower edge to afford a firm foundation. Said trap-front or cornerpiece is also cast with the laterally-projectin g lugs, havingperforations for the passage of bolts, in order to secure the same and the curb-sections together, and at its lower edge an opening of'suflicient size is left for the free passage of the water into the sewer. The upper edges of the sections and corner-pieces are formed with a series of spurs, H, to allow the water to run off, and serve as an ornament to the pavement.

By conining the sections to a suitable foundation it will be evident that there is no liability of the curbing settling, and it will moreover be observed that the sections constructed as described, are susceptible of being cast in a single piece, and while possessing great strength they are also extremely light, being cast of at sections.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s
